Description

Technical Field

[0001] The utility model relates to a special-shaped pipe for installing accessories, which is mainly used in the technical field of special-shaped pipes. Background Art

[0002] Bicycles are a commonly used means of transportation. They are powered by human power, without the need for electricity or gasoline. They are very environmentally friendly and are very suitable for use as general transportation or leisure sports equipment. Since bicycles are both energy-free and exercise-free, more and more modern people use bicycles as a means of transportation. With the development of various accessory technologies applied to bicycles, riders often install various electronic accessories such as lights, stopwatches, mobile phone holders, driving recorders, display screens or sports cameras on the bicycle's stem or handlebars. In particular, in order to enhance the safety and comfort of bicycle riders, it is becoming increasingly important to install accessories such as turn signals or brake lights to provide instructions. In addition to the traditional function of indicating the position of the vehicle behind when the weather is bad or the sky is dark, the taillight device of the bicycle also further informs the vehicle behind to turn or brake, which can further enhance driving safety.

[0003] However, in order for the bicycle taillight to light up the corresponding light when turning or braking, the bicycle taillight needs to be connected to the rider's manual light switch or a taillight controller that can detect the driving conditions and automatically control the light by a signal line. However, the taillight devices currently on the market are usually not integrated with the bicycle frame, and the signal line used to control the bicycle taillight is often exposed to the outer surface of the bicycle body. Therefore, not only is the weather resistance poor, but it is also easy to be accidentally touched and pulled during driving, causing trouble to the cyclist. Therefore, a bicycle taillight with hidden wiring has emerged.

[0004] For example, in Taiwan Patent Publication No. M650988 and No. M476739, at least one mounting hole is formed on the peripheral wall of the bicycle seat tube at the rear relative to the frame for installing a lamp holder, so that the lamp holder and its wires can be hidden in the seat tube; however, the setting of the mounting hole has destroyed the structural strength of the entire seat tube, and because the lamp holder is connected to the mounting hole, the mounting hole needs to further withstand the connection stress, which can easily cause the area to be unable to withstand the force for a long time and unable to cope with sudden and instantaneous forces, resulting in breakage, bending or deformation, making it impossible for the rider to ride smoothly, and further improvements are needed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a special-shaped pipe for installing accessories, whose cross-section is a pipe body with unequal wall thickness, so that the stress source can be borne by the thickened section of the pipe wall, thereby improving driving safety and overcoming the shortcomings of the prior art.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a special-shaped tube for installing accessories, the special-shaped tube is assembled on the frame of a bicycle, the top end of the special-shaped tube has a joint for pivotally connecting the seat of the bicycle; the tube body of the special-shaped tube has at least one through hole for installing accessories, and at least one side edge of the through hole has a tube wall thickened section.

[0007] Preferably, the through hole has upper and lower side edges which are opposite to each other, and two side edges connecting the upper and lower side edges, and the upper and lower side edges have tube wall thickened sections.

[0008] Preferably, the longitudinal direction of the tube wall thickened section extends from above the through hole to the bottom of the special-shaped tube.

[0009] Preferably, the two side edges have tube wall thickened sections.

[0010] Preferably, the accessory has at least one clamping member, which is clamped and fixed to the thickened section of the pipe wall.

[0011] Preferably, the tube body of the special-shaped tube has another tube wall thickening section on the other side relative to the through hole.

[0012] The beneficial effect of the utility model is that through the display of the above-mentioned technical means, the thickened section of the tube wall can be used as a portion for joining with accessories, thereby improving the structural strength of the joint between the seat tube and the accessories, enhancing the safety of bicycle use, and hiding the wiring of the accessories in the special-shaped tube, thereby preventing the wiring from being exposed to wind and rain, or being accidentally touched and pulled during driving.

[0013] The utility model is further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] This invention can be used to install special-shaped pipes with accessories, such as Figure 1As shown, in the present invention, a special-shaped tube 1 is assembled on the frame of a bicycle, and a joint 2 is provided at the top end of the special-shaped tube 1. The joint 2 includes a seat bow clamping portion 21, which is used to clamp a set of seat bows (not shown) of a seat cushion to pivotally connect the seat cushion of the bicycle (not shown).

[0020] The key point of the invention is that the tube body of the special-shaped tube 1 has at least one through hole 11 for installing accessories, and at least one side edge of the through hole 11 has a tube wall thickening section 12. In the embodiment shown in the figure, the through hole 11 has upper and lower side edges 111 and 112 opposite to each other, and two side edges 113 connecting the upper and lower side edges 111 and 112. Please also refer to Figure 2 As shown, the upper and lower side edges 111 , 112 have a tube wall thickened section 12 , and the longitudinal direction of the tube wall thickened section 12 extends from above the through hole 11 to the bottom of the special-shaped tube 1 .

[0021] like Figure 3 and Figure 4 As shown, the accessory 3 has at least one clamping piece 31. In the embodiment shown in the figure, the upper and lower sides of the accessory 3 are respectively provided with clamping pieces 31. The accessory 3 enters the through hole 11 and is clamped and fixed to the tube wall thickening section 12 by the clamping piece 31, so that the accessory 3 is fixed to the tube body of the special-shaped tube 1, so that the accessory 3 is partially embedded in the special-shaped tube 1 to be integrated into the bicycle frame, and the wiring 32 of the accessory 3 can be hidden in the special-shaped tube 1, thereby preventing the wiring from being exposed to wind and rain, or being accidentally touched and pulled during driving; in particular, the special-shaped tube of the present invention can use its tube wall thickening section 12 as a portion for joining with the accessory 3, especially for being clamped and fixed by the clamping clip 31 of the accessory 3, so that the stress source is borne by the tube wall thickening 12, that is, the structural strength of the joint between the special-shaped tube 1 and the accessory 3 is improved, and the safety of bicycle use is improved.

[0022] Furthermore, if Figure 4 As shown, the tube body of the special-shaped tube 1 has another tube wall thickening section 12 on the other side of the through hole 11d; or Figure 5 As shown, the two side edges 113 have a tube wall thickening section 12, that is, the tube wall thickening section 12 is annular and relatively located at the entire outer periphery of the through hole 11 (including the upper and lower side edges 111, 112, and the two side edges 113).
